    • The invention relates to an arrangement in connection with a central lubrication system. The arrangement includes a lubricant vessel, a pump unit, a control unit, pipe systems, a pressure monitor unit, at least one lubricant feeder provided with at least one piston which moves due to the influence of the pressure of a lubricant present in the pipe system/object to be lubricated, and a movement monitor unit to monitor the operation of the feeder. The movement monitor unit includes a sensor part mounted to a nipple manufactured from a weakly magnetable material. The nipple includes a permanent magnet to generate a magnetic field, and a sensor for detecting movement of the piston, and an electronics part which processes a signal received from the sensor and forwards this processed signal to the control unit.

    • A fluid flow sensor is provided for use in a remote location from a fluid delivery system, such as a lubricant or grease delivery system for lubricating parts. The fluid flow sensor includes a body defining a lubricant conveying passageway having a seat, and a poppet configured to engage the seat. The poppet is biased against the seat by a spring, but is moveable off the seat when fluid is moved through the passageway. The poppet includes a rod that extends upstream from the poppet through an aperture in the passageway, and a piston is positioned abuttingly against the end of the rod and biased against the rod by a spring so that the piston will move with the poppet as the poppet is moved off the seat in a first direction. A proximity switch is positioned perpendicularly to the first direction adjacent the piston. The piston is adjustable along the first direction, and the proximity switch is adjustable in the perpendicular direction, such that the sensitivity and hysteresis of the sensing arrangement can be adjusted and set to desired levels. By this arrangement, fluid quantities of as little as 0.001 cubic inch can be accurately sensed at an actuation or cycle frequency of about 100 milliseconds.
    • 提供流体流量传感器,用于远离流体输送系统的位置,例如用于润滑部件的润滑剂或润滑脂输送系统。 流体流量传感器包括限定具有座椅的润滑剂输送通道的主体,以及配置成接合座椅的提升阀。 提升阀被弹簧偏置在座椅上,但是当流体移动通过通道时,提升阀可以从座椅上移动。 提升阀包括一个杆,该杆从提升阀的上游延伸通过通道中的一个孔,并且一个活塞靠近杆的端部定位,并通过一个弹簧偏压到杆上,使得活塞随着提升阀作为提升阀一起移动 在第一方向上离开座椅。 接近开关垂直于邻近活塞的第一方向定位。 活塞可沿着第一方向调节,并且接近开关在垂直方向上是可调节的,使得感测装置的灵敏度和滞后可被调整并设定到所需的水平。 通过这种布置,可以在约100毫秒的致动或循环频率下精确地感测到少至0.001立方英寸的流体量。

    • The invention relates to an arrangement in connection with a central lubrication system, the arrangement comprising a lubricant vessel, a pump unit, a control unit, pipe systems, a pressure monitor unit, at least one lubricant feeder pro-vided with at least one piston (5) which moves due to the influence of the pres-sure of a lubricant present in the pipe system/object to be lubricated, and a movement monitor unit to monitor the operation of the feeder. The invention is characterized in that the movement monitor unit comprises a sensor part (3) mounted to a nipple (4) manufactured from a weakly magnetable material. The nipple (4), in turn, comprises a permanent magnet (2) in order to generate a magnetic field, and a sensor (4) for detecting movement of the piston (5), and an electronics part (13) which processes a signal received from the sensor (4) and produced as a result of a change in the magnetic field caused by the movement of the piston (5) with respect to the sensor part (3), and forwards this processed signal to the control unit.
